On my systems with no configuration at all the Meta key is adding the
eight bit to the ascii table.
So, if you press the letter d, which is 01100100 you get the letter d on
your display. If you press the letter d while you keep pressed the Meta
key, you get 11100100, which according to your fonts can be a with 2
dots (for latin1, latin2, latin9, latin10).
Similar if you press Q (01010001) while Meta is on, you get 11010001
which can be N with ~ (latin1, latin9) or N with acute (latin2,
latin10).
Meta-$ will give you currency in latin1 and latin2, and euro in latin9
and latin10. $ is ascii 00100100, and currency/euro is 10100100.
This mechanism is for xterm, if the .Xdefaults file contain (by default
it does):
*VT100.Translations: #override \
Meta<KeyPress>:insert-eight-bit()
I fail to find any use of this meta key. I use Shift and AltGr only.
(Also Alt and Ctrl). No meta, super or hyper.
